In the realm of family law, disputes often involve intricate familial dynamics that require resolution through the Family Court. When a dispute arises, it may involve parties beyond the initial applicant and respondent. In such cases, making a joinder application becomes crucial for ensuring all relevant parties are included in the legal proceedings. Understanding the process of making a joinder application is fundamental for navigating the complexities of the family court system effectively.


What is a Joinder Application?

A joinder application is a legal process through which additional parties are brought into existing legal proceedings. In the context of family law, this typically occurs when someone who is not initially part of the case has a significant interest or involvement in the matters being discussed. The purpose of a joinder application is to ensure that all relevant parties are present and represented in the legal process, thereby allowing for a fair and comprehensive resolution of the dispute.


When to Make a Joinder Application?

There are various scenarios in family law where making a joinder application may be necessary:

  • Third-party involvement: When a third party, such as a grandparent or another relative, has a significant interest in the welfare of a child involved in custody or visitation proceedings.
  • Financial interests: In cases involving the division of assets or financial matters, there may be additional parties with financial interests that warrant inclusion in the proceedings.
  • Parental responsibility: If there are questions regarding parental responsibility or guardianship, parties who may have a claim to such rights could be joined to the case.
  • Domestic violence or abuse: In situations where allegations of domestic violence or abuse involve parties beyond the petitioner and respondent, those individuals may need to be joined to the proceedings to ensure their safety and rights are protected.


How to Make a Joinder Application?

Making a joinder application involves following specific procedures set out by the family court. While the process may vary slightly depending on the circumstances of the case, the following steps generally apply:

Prepare the application: Clearly outline the reasons why the additional party should be joined to the proceedings. This may involve drafting a formal application or petition to be submitted to the court.

File the application: Submit the application to the Family Court where the existing proceedings are taking place. Ensure that all relevant documentation is included and that the application is filed within the specified timeframes.

Serve notice: Once the application is filed, it must be served on all parties involved in the existing proceedings, as well as the party being joined. This ensures that all parties are aware of the joinder application and have an opportunity to respond.

Attend court hearings: Depending on the circumstances of the case, the court may schedule a hearing to consider the joinder application. All parties involved will have the opportunity to present their arguments and evidence before the court makes a decision.

Court decision: Following the hearing, the court will make a decision regarding the joinder application. If the application is granted, the additional party will be formally joined to the proceedings, and the case will proceed accordingly.



Navigating the family court system can be a complex process, particularly when additional parties need to be involved in the proceedings. Making a joinder application is an essential step in ensuring that all relevant parties are included and heard in the resolution of family disputes. By understanding the process and following the necessary steps, individuals can effectively navigate the legal complexities of family law and work towards a fair and equitable resolution for all involved.

If you are considering making a joinder application, you will need the court to grant you permission to be joined to the proceedings so it is important that you make a robust application with supporting  evidence.
